Depending on their time delay from the primary events with which they are associated, multiple reflections are characterized as short-path or peg-leg, implying that they interfere with the primary reflection, or as long-path, where they appear as separate events. Usually, primary reflections are simply called reflections or primaries, whereas multiple reflections are simply called multiples. Multiple reflections (or reverberations) between the water surface (i.e., the interface between air and water) and the water bottom (i.e., the interface between water and solid) are common in marine seismic data.
